Using a Poisson process we stochastically generate many realisations of ground motion based on the hazard model to estimate the probability of observing the historical intensities, including uncertainties between instrumental ground motions and intensity observation. From our results we cannot statistically reject Indonesia\u2019s current PSHA for key cities in Java; however, they do suggest that seismic hazard may be underestimated for the megacity Jakarta. Identification of plausible source models for large damaging events through scenario ground motion modelling is used to test if the seismic source model for the current PSHA captures the location and magnitude of historical earthquakes. The results demonstrate that the current PSHA underestimates maximum magnitudes on a number of presently mapped faults, including the Flores Thrust, and for intraslab events.\nPoster presented at the10th International Workshop on Statistical Seismology 2017", "num_resources": 1, "num_tags": 5, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/testing-indonesias-national-seismic-hazard-assessment-using-historical-intensity-data", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[95.013, -10.923], [140.98, -10.923], [140.98, 5.9101], [95.013, 5.9101], [95.013, -10.923]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[95.013, -10.923], [140.98, -10.923], [140.98, 5.9101], [95.013, 5.9101], [95.013, -10.923]]]}", "state": "active", "temporal_coverage_from": "2025-09-09 06:51:26.056+00", "title": "Testing Indonesia\u2019s national seismic hazard assessment using historical intensity data", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "8e8c354a-4d7a-4d87-94b9-1891c56383bf"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-17T00:01:21.455459", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Page 65 of the pdf", "format": "PDF", "hash": "", "id": "ef73c64c-30d6-41fb-9638-80ae9e857cb2", "last_modified": null, "metadata_modified": "2025-10-17T00:01:21.420323", "mimetype": null, "mimetype_inner": null, "name": "LInk to Abstract", "package_id": "a095753e-6aeb-42d8-8634-017e3e94deee", "position": 0, "resource_locator_function": "browsing", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://iris.unipa.it/retrieve/e3ad891b-79ef-da0e-e053-3705fe0a2b96/Statsei2017%20proceedings.pdf", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "EARTH SCIENCES", "id": "927af2a7-7457-45c2-bd55-10000fd09c14", "name": "EARTH SCIENCES", "state": "active", "vocabulary_id": null}, {"display_name": "Indonesia", "id": "930e3298-ccc9-41b1-9804-bce922e0ad02", "name": "Indonesia", "state": "active", "vocabulary_id": null}, {"display_name": "national probabilistic seismic hazard assessment - PSHA", "id": "b1b5a40c-fd12-4e67-b892-5310fa42b9fc", "name": "national probabilistic seismic hazard assessment - PSHA", "state": "active", "vocabulary_id": null}, {"display_name": "national seismic hazard", "id": "922e0a36-13cc-46cc-b882-f83bdc240808", "name": "national seismic hazard", "state": "active", "vocabulary_id": null}, {"display_name": "seismic hazard assessment", "id": "20a91d12-1822-40f5-874d-55b459aecd58", "name": "seismic hazard assessment", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
